problems with manifold LHD engine into RHD car

[norway_triumph]

Here is the project

bought a RHD Manta B - previous 2,0 auto - but with no engine/box

as i'm living in norway , i just couldnt get my hand on a autobox

so i bought a donor LHD GTE with 2,0 injection

Transfered everything needed and got the engine running

BUT there is no room for the exhaust manifold (fouling the steering)

So i tried to cut and weld the original manifold that came with the injection engine , but no luck - although i have fitted it-  the exhaust just doesnt seem to get out good enough - so the engine doesn't run smooth (backpressure) . Without the manifold the engine runs smooth (tho noisy ) .

So here is the Questions (finally ) -

1 is there any difference between the lhd/rhd injection exhaust manifolds  ? ?

2 where can i get a RHD manifold (if anyone have one for sale i could give you a uk adress to send it to if you dont want to be bothered sending it to norway)

Can you take a picture of the manifold you have there please ?  It would help to see what you have got there so I can tell what you need.

[mikemanta]

yes the manifolds are different between lhd and rhd as are the exhaust down pipes for the reason of the steering

Wouldn't it be worth using the donor car to convert your car to left-hand drive?

RHD cars the exhaust manifold has the exits in front of the other.

LHD cars had the exits side by side

thanks for the replies , must post a wanted ad for a manifold then

1900S - the car is a crayford conversion so i would rather keep it original ,

So is it a Centaur Convertible?

So is it a Centaur Convertible?

yes

previously ran with a rover v8 as well.. but i'm taking it back to close to original . this is however my first Opel so don't know all the differences between the models yet -  im more into morris/austin/ford/vauxhall

here it is in as found state

That's a very rare Manta! I think there were only a bit more than a 100 cars made of.

The double slot nose is not original (it must have a B1 nose), but the rims look great at the car.

I've got the same opinion: keep it original.

thanks. yes its rare , they build 200 combined cavalier / opel. its estimated that there were about 10% opek, and the rest was vauxhalls. the nose was changed sometimes during the 90s - but i will leave it like this

There was a period when two slot noses and plain Cavalier noses where un-available, i have seen a Vauxhall Cavalier MK 1 that had accident damage repairs done in this period and that was fitted with a Four Slot nose, it did look very strange !

i also have a mk1 cavalier rhd with the plain nose and 1.9 carb engine, but theres still al ot of parts thats the same - saving me for keeping a huge stock of spare parts
